Product Overview

PFP Photosensitive Single-Mode Medium-NA Fiber

PFP photosensitive fibers are designed to reduce grating-writing times associated with industry-standard telecommunication fiber and can be easily spliced. These photosensitive fibers provide cost-savings for grating-writing because customers can write highly repeatable, quality gratings in a short time.

Applications
WDM Gain flattening filters Dispersion compensators Pump stabilizers

Features & Benefits
Enhanced photosensitivity - Shorter grating writing time Mode-matched to transmission fibers - Low splice loss Tightly controlled specifications - Excellent uniformity
